We’ll never complain when salt on the road keeps our cars and trucks from slipping and sliding in bad weather. But when our beauty of an automobile starts showing signs of rusting with age, it’s a horrible sight to see.
Salt speeds up the corrosion of metal because it attracts water and can cause it to settle. Water accelerates the transfer of electrons from one substance to another. The oxygen in both the water and salt gradually change the metal to metal oxide, which over time turns your beloved set of wheels into an old rust bucket.
The places on your cars and trucks which usually suffer the most rust damage are doors, fenders, the hood and tailgate. The undercarriage of your vehicle is susceptible as well.
Fortunately, having your vehicle washed with frequency will greatly reduce the incidence of rust damage. It’s recommended that you wash it at least once every ten days to protect your investment.
At Double R Car Wash, our undercarriage cleaners will clear off salt and sand below and the full wash will take care of your other external areas as well. One important piece of the equation is to make sure your vehicle is as dry as possible following the wash.
In between washes, try to keep your ride dry, and avoid driving through tall snow, as that can lodge moisture in difficult to reach areas.
Great article & explanation of the science behind corrosion. I’ve been a rust consultant for decades and can agree that cleaning the salt off your car or boat with tap water is well worth the effort to protect your investment.
